The superficial middle cerebral veins (SMCV) of 50 human heads were dissectedunder the operating microscope (10?).There were 122 terminal braches of the SMCV in the specimens and the typesof their drainage can be divided into four:type 1 (41.00%)—drains into the caver-nous sinus;type 2 (24.60%)—drains into the variant venous sinus in the lateralwall of the cavernous sinus;type 3(28.70%)—drains into the variant venous sinus inthe dura of the middle cranial fossa;type 4(5.70%)—drains into other dural venoussinuses.Type 1 may be considered as normal and the others as variant.The two variant dural venous sinuses reported are respectively located in thelateral wall of the cavernous sinus,named“the lateral wall sinus of the cavernoussinus”,and in the dura of the middle cranial fossa,named the“variant sinus ofthe middle cranial fossa”.The former occurred 27% in the specimens and the later25%.We have discussed about the drainage of the SMCV and two variant dural ven-ous sinuses on the embryonic basis and the clinical practice.

BACKGROUND: It is demonstrated in modern pharmacologic study that total paeony glycoside (TPG) provides extensive pharmacologic activities,such as inhibiting aggregation of platelets and erythrocytes, anticoagulation,antithrombsis, anti-arterial sclerosis, protecting heart and liver, anti-tumor,etc.OBJECTIVE: Neonatal rat cardiomyocytes were cultured in vitro and by the changes of superoxide dismutase (SOD) activity, malondialdehyde (MDA) and nitric oxide (NO) contents in cell culture solution, the protection of TPG on injured cardiomyocytes was analyzed.DESIGN: Controlled observation was designed.SETTING: Bioengineering Department in School of Life Science and Technology of Xi 'an Jiaotong University and Institute of Bone Diseases in Medical School of Xi'an Jiaotong University.MATERIALS: The experiment was performed in Bioengineering Department in School of Life Science and Technology of Xi 'an Jiaotong University from February to June in 2003, in which, 44 SD neonatal rats aged 1-3 days were employed. The 48-hour-cultured cardioryocytes were prepared in 42 bottles and randomized into 6 groups, named normal control (normal group), medicated-injury group (injury group), TPG 0.625 mg/L group,TPG 3.125 mg/L group, TPG 15.625 mg/L group and positive control, 7 bottles in each group.METHODS: Cardiomyocytic primary culture was performed under aseptic condition. No any drug was used in normal group, isoprenaline was added in injury group to terminate the concentration at 100 mg/L, in TPG 0.625, 3.125 and 15.625 mg/L groups, 30 minutes after isoprenaline added, RGP at dosages of 0.625, 3.125 and 15.625 mg/L were added respectively; in positive control, 30 minutes after isoprenaline added, coenzyme Q10 was used to terminate the concentration as 100 mg/L.Afterwards, the assay of every index was performed. Xanthine oxidase (XOD) method was used to assay SOD activity, thiobarbituric acid (TBA)method was to assay MDA content and nitrate reductase (NR) method was to assay NO content.cell culture solution in each group.Compared with normal group, the levels of total SOD, CuZn-SOD and MnSOD were reduced remarkably in injury group (P ＜ 0.05 or P ＜ 0.01).The above-indexes in every TPG group and positive control were improved to different extents (P ＜ 0.05 or ＜ 0.01), in which, the protection of TPG 15.625 mg/L group was near to or superior to positive control [(79.50±10.67), (80.30±13.50); (48.24±13.26), (49.73±10.23); (31.26±10.22),in cell culture solution in each group: Those in injury group were higher remarkably than normal group (P ＜ 0.01). MDA and NO contents were all reduced in every TPG group and positive control and dose dependence presented in TPG protection, the higher the dose was, the stronger the action of TPG on protection was, in which, in high-dose group, MDA content was near to normal group [(5.41±1.81), (4.48±0.94) μmol/L, P ＞ 0.05] and NO content was similar to positive control [(81.83± 9.08), (82.41±12.37) mol/L,P ＞ 0.05].CONCLUSION: TPG protects myocardial injury induced by isoprenaline,indicating dose-dependence relationship, which is probably associated with enhanced anti-oxidation of cell, reduced injury of cellular membrane induced by free radical and lipid oxidant.

Aim To investigate the antioxidative effect of total paeony glycoside(TPG) on cardiomyocytes injured.Methods The ischemia and hypoxia injuy model of cultured neonatal rat cardiomyocytes was induced by adding isoprenaline(ISO), and superoxide dismutase(SOD), malonalde hyde(MDA) and nitric oxide(NO) in the culture solution of normal control group; ISO injure group, CoQ 10 positive control group as well as protective group s with high,middle or low-dose TPG were respectively analyzed and compared. Results Compared with normal control group,the enzyme activity o f total SOD, CuZn-SOD and Mn-SOD decreased obviously, and the content of MDA and NO increased markedly in injury group, but in TPG and CoQ 10 groups all of detective indicators had improvement in varying degrees, and the protective effect was better than or close to positive control group in high-dose TPG grou p.Conclusion TPG has protective action on injured cardiomyocyte s induced by ISO in dose-dependent manner. The mechanism relates to the enhance ment of antioxidative effect in cells, and the reduction of membrane damage caus ed by free radical and lipid peroxide.

This study examined the association of pregnancy with urolithiasis and provided new insights into urolithiasis in pregnancy. A total of 462 subjects were studied from January 2004 to December 2009 in Foshan Maternal and Child Health Hospital, China. Among the 462 subjects, 162 cases of urolithiasis during pregnancy (UPG) were selected as the observation group, 150 cases of no urolithiasis during pregnancy (NUPG) served as pregnancy control group, and 150 cases of no pregnancy (NPG) at reproductive age who took part in physical examination were randomly assigned into non-pregnant control group. At the same time, the patients in observation group were divided into the following sub-groups: no symptomatic urinary calculus (NSUC) and symptomatic urinary calculus (SUC) groups; SUC group was further divided into surgical intervention (SI) and conservative management (CM) groups. The general information and the data of blood and urine were collected and compared among the groups. The results showed that the incidence of urinary calculi in pregnant women was lower than that in non-pregnant women, the formation of urinary stone was associated with the change of metabolism of protein and sugar in pregnant women, and the surgical intervention was a practicable alternative to treat the clinical intractable symptomatic urinary calculi in pregnancy.

Objective To evaluate the diagnostic value of magnetic resonance enterography(MRE)and ectopic gastric mucosa imaging(EGMI)in children with lower gastrointestinal hemorrhage.Methods The clinical data including gender,age,amount of bleeding and preoperative minimum hemoglobin(Hb)levels of 54 children with lower gastrointestinal hemorrhage were collected,who received surgical exploration in Department of Pediatric Surgery,Anhui Provincial Children's Hospital between February 2014 and April 2016.Children were divided into lesion group and non-lesion group according to the findings of surgical exploration.Lesion group were defined as children with Meckel's diverticulum(MD)or duplication of the small intestine by surgery and postoperative pathological findings.A total of 36 cases,25 cases of boys,11 cases of girls,aged(2.86±1.59)years old.Non-lesion group were defined as children,who underwent operation with negative result or with lesions but not MD or duplication of the small intestine.A total of 18 cases,14 cases of boys,4 cases of girls,aged(3.87±1.62)years old.MRE and EGMI were performed when the children stopped bleeding,before the inspection,should fasting for 4-6 h.SPSS 13.0 software was used for statistical processing.The evaluation of EGMI,MRE and the both in diagnosing MD or duplication of the small intestine were conducted by receiver operating characteristic curve(ROC).According to the principles of biggest gain best diagnostic value by Youden index,and the degree of sensitivity and specificity was calculated at this time,P<0.05 for the difference was statistically significant.Results There was no significant differences statistically in gender between 2 groups(x2=0.415,P>0.05).There were statistically significant differences in age,amount of bleeding and preoperative minimum hemoglobin levels(t=2.179,2.027,2.222,all P<0.05).There were statistically significant differences in classification comparison by EGMI and MRE between 2 groups(x2=15.226,29.121,all P<0.01).The optimal cut-off value of EGMI and MRE in the diagnosis of enteric malformation was more than level 3,and the suspected positive and being positive value was assigned as positive results.According to the cut-off value above,EGMI,MRE and EGMI plus MRE in series and in parallel in the diagnosis of enteric malformation,the areas under curves(AUC)were 0.809,0.917,0.750 and 0.847,respectively.The sensitivity was 61.1％,75.0％,55.6％and 80.6％,respectively.The specificity was 90.4％,94.4％,94.4％and 88.9％,respectively.The Youden's indexes were 0.515,0.694,0.500 and 0.695,respectively.The optimal cut-off value of age and preoperative minimum hemoglobin levels in the diagnosis of enteric malformation were 2.92 years and 80 g/L,respectively.The AUC was 0.761 and 0.672.The Youden's indexes were 0.515 and 0.333.There was no significant differences statistically in AUC compared with age,MRE and EGMI(all P<0.05).Conclusions The high diagnostic value in children with lower gastrointestinal hemorrhage is found by using MRE and EGMI.Then,MRE as a separate diagnosis method is also worthy of clinical application.

Objective To detect the relationship between the pathological degrees of chronic cholecystitis and coincident diseases. Method The pathological degree was divided into mild,moderate and severe degree according to the pathological changes in 442 cases of chronic cholecystitis,and the proliferation of mucosa cell was detected by SP immunohistochemical staining in 105 cases. Results The coincident calculus, polyp, adenoma in the mild chronic cholecystitis were 65.0%,17.1% and 0.5%, respectively. The coincident calculus, polyp, adenoma and malignant neoplasms in the moderate chronic cholecystitis were 70.1%, 19.4%, 3.7% and 2.2%. The coincident calculus, polyp, adenoma and malignant neoplasms in the severe chronic cholecystitis were 88.0%, 26.4%, 24.2% and 9.9%. The positive expression rates of PCNA in mild, moderate and severe chronic cholecystitis were 12.3%, 17.5% and 38.7%, respectively. The results showed that the pathological degree of chronic cholecystitis was obviously related to the coincidence of calculus, polyp, adenoma, malignant neoplasms. Conclusions Severe chronic cholecystitis is a high-risk lesion of gallbladder carcinoma,it should be removed surgically.
